Sectional sash guide



Patented Apr. 26, 1932 t at stars FATE FF'EQE SEGTIONAL SASH GUIDE Application filed May 31, 1930, Serial No. 458,510, and in Canada May 9, 1930.

This invention relates to improvements in sectional sash guides of the character disclosed in my co-pending application, Serial No. 455,851, filed May 26, 1930.

The object of the present invention is to provide a novel link suspension whereby the lower guide section is supported for swinging movement into and out of alignment with the upper guide section.

A further object is to provide a generally improved construction in which the link suspension for the lower guide section is concealed from view when said guide sections are in aligned position. 7

Other objects, advantages and characteristic features of the improvements provided by the present invention will be more readily understood from the following detailed dis cussion taken in connection with the accompanying drawings, wherein Figure 1 is a side view of a guide assembly constructed in accordance with the present invention. In this view the upper and lower guide sections are shown in their aligned or sash guiding position.

Figure 2 is a view similar to Figure 1, but looking towards the opposite side of the assembly.

Figure 3 is a View similar to Figure 1, but showing the lower guide section swung outwardly to a laterally displaced position with reference to the upper guide section.

Figure 42 is a view similar to Figure 3 showing the manner of applying the assembly to a window frame.

Figure 5 is a sectional view taken on the line 55 of Figure 4.

With the exception of the link suspension, the general assembly of the guide sections shown in the present drawings is substantially the same as set forth in my prior application previously referred to. The guide sections and 11 are carried by a base strip adapted to be attached to one of the window j ambs. This base strip comprises aweb 12 provided with amb engaging flanges 13 and 14:. Each of the guide sections comprises flanges l5 and 16 connected by an intervening web 17. The base strip is also provided with a weather-proofing flange 18 formed as a reverse continuation of the flange 14 and adapted to overlap the flanges 16 of the guide sections 10 and .11 when said sections are disposed in the position shown in Fig. 1. The guide sections 10 and 11 are also provided with similar weatherprooflng flanges 19 formed as continuations of the flange and adapted to overlap the flange 12-3 of the base strip. The webl'? oi"- the upper stationary guide section 10 is fastened to the web 12 of the base strip by screws or other fastening devices indicated at 10a in Figs. 1 and 2. v

The lower guide section 11is supportedby links'20 and 21. Each link has one end. pivoted to a block 22carried by said guide section and the other end pivoted to a block 23 carried by'the flange 1d of the base strip. The links and 21 operate in suitable slots 24 formed by omitting portions of the flange 13 of'the base strip. The link 21 is made shorter t-ha-n the link 20 so that the guide section 11 is supported for swinging movement from the position shown in Figures 1 and 2 to the dotted line position shown in Figure 4. When the guide section 11 is in the last mentioned position, it will be noted thattho lower end of said section is swung inwardly into engage ment with the weatherproofing flange 18 of the base strip and that the pivot 21a of the link-'21 occupies a position between the flange 18 and the vertical centre of the pivot 217) so that the guidesection 11 will retain the dotted line position shown in Figure 4 when moved thereto. In this dotted line position of the section 11, the upper end of the link 21 is received in a recess 25 formed by cutting away part of theweb 12 of the base strip. [is explained more particularly in my prior application, the lateral displacementof the guide section 11 with reference to the guide section 10 is of advantage in that it facilitates removal of the lower sash normally operating in the guide channel conj ointly aflorded by said guide sections. The link suspension shown in the instant application isof particular advantage. in that it provides a supporting means for the displaceable lower guide section which is. arranged to. be concealed from view; when the lower guide section is aligned with: reference to. the upper:

guide section. Another advantage of this link suspension is that it takes the place of the unsightly stop lug arrangement disclosed in my prior application.

The manner of applying the guide assembly to a window frame is clearly shown in Figure 4. The base strip is secured to the jamb 2? by screws 28 passing through the web 12 which is spaced from the jamb by the flanges 13 and 11-. The head of the screw indicated at 28 is adapted to engage in complementary recesses 29 framed in the nieeting ends of the guide sections 10 and 11 to releasably secure said sections in aligned position.

Having thus fully described what I now conceive to be the preferred embodiment of my invention, it will be readily understood that variouschanges may be resorted to within the scope and spirit of the appended claims.

Having thus described my invention, what I claim is:

1. A sash guide comprising complementary sections provided with sash engaging means and upper and lower links supporting one of said sections for swinging movement into and out of alignment with the other section.

2. A sash guide as recited in claim 1 in which one or" said links is shorter than the other.

3. A sash guide as recited in claim 1 in which the lower link is shorter than the up per link.

4. A sash guide comprising upper and lower complementary guide sections of channel form, a base strip to which the upper guide section is secured in a stationary manner, and links connecting the lower guide section to the base strip in a manner permitting said lower guide section to swing into and out of alignment with the upper guide section. V

5. A sash guide comprising upper and lower guide sections of channel form, a base strip to which the upper'guide section is secured in a stationary manner, links connecting the lower guide section to the base strip in a manner permitting said lower guide section to swing into and out of alignment with the upper guide section, and weatherproofing flanges serving in the aligned position of the guide sections, to retard the passage of air between the engaging surfaces of the guide sections and the base strip.

6 A sash guide comprising upper and lower guide sections of channel form, a base strip to which theupper guide section is secured in a stationary manner, links connecting the lower guide section to the base strip in a manner permitting said lower guide sec tion to swing into and out of alignment with the upper guide section, said guide sections being provided at one side with extended weatherproofing flanges engageable with the adjacent side of the base strip and the opposite side of the base strip being provided with similar projecting water proofing flanges engageable with the adjacent sides of the guidesections.

7. A sash guide assembly comprising a metal base stripincluding a web, side flanges projecting in one direction from the web for engagement with the jamb of a window frame, aweatherproofing flange projecting in the opposite direction from the web and formed as a reverse continuation of one of said side flanges, an upper guide section of channel form secured to the web of the base strip so as to be stationary thereon and a lower guide section of channel form pivoted to the web of the base strip forswinging movement into and out of alignment with the upper guide section, each of said guide sections being formed from a sheet of metal bent to form a web and a'pair of side flanges projecting therefrom and adapted to receive a window sash therebetween, the flanges at one side of the guide sectionsbeing engageable with the weatherprooflng flanges of the base strip in the aligned position of said guide sections and the flanges at the opposite sides of the guide sections being reversely bent to provide extended weatherproofing flanges engageable with the adjacent side flange of the base strip.

In witness whereof, I have hereunto set my hand.
